手术时无肿瘤残余迹象的胃癌患者,腹膜转移依然是最常见的复发类型,也是治愈胃癌的主要障碍。一般认为这是由于胃原发癌侵及浆膜表面,从而发生癌细胞微观扩散所致。手术时对腹膜冲洗液进行细胞学检查可发现脱落癌细胞。但至少50％死于腹膜复发的病人其细胞学检查阴性。很显然,细胞学检查依赖于取样方法和检测技术,因此对胃癌术后的预后意义不大。
In patients with gastric cancer without residual signs of surgery, peritoneal metastasis is still the most common type of recurrence and is a major obstacle to cure gastric cancer. It is generally believed that this is due to the invasion of the primary gastric cancer to the surface of the serosal membrane and the resulting microscopic proliferation of cancer cells. Cytological examination of the peritoneal lavage fluid during surgery revealed shedding of cancer cells. However, at least 50% of patients who died of peritoneal recurrence had negative cytology. Obviously, cytology depends on sampling methods and detection techniques, so it has little significance for the prognosis of postoperative gastric cancer.
